Abstract：

To solve the problems of backward forging technology and equipment, poor working environment for operators and low production efficiency of turnout rails, a special double-station induction heating system, automatic loading and unloading system of rail, four-station integral die, transverse automatic mold changing mechanism and control system were researched and developed by analyzing the forging process and requirements of turnout rail, and the automatic control production line for hot forging for rail was established. After on-line debugging of system, the automatic production of loading, heating, feeding, forging and unloading for rail was realized by using this production line, which greatly reduced the labor intensity of operators, improved the production efficiency and product quality, and improved the working environment of workers. Finally, the forging test of 60AT1 rail show that the forging time of single rail is reduced from 20 min to 9 min, and the number of operators per shift is reduced from six to three, and the product quality is qualified and the state is stable, which verifies that the scheme can be used in the forging automatic production of railway turnout rail.
